I have a 60 year old house, the attic appears to be dry and free of mold.
Recently while crawling around, I noticed that the cold air return duct had a large hole in it meaning that much of the furnace air is being drawn from the attic. I thought about sealing the hole, then wondered if perhaps it was improving circulation in the attic and if I closed it, I might have circulation problems in the future.
I'd appreciate any input re possible problems leaving the hole open, I've no idea how long it's been there.
Thanks
